Vacuum line troubles
Does anyone have detailed pics of the vacuum lines in the area of the EGR valve on a 94 GT?
I have 2 very small diameter hard plastic ones coming from a harness under the upper intake and one normal rubber one from the intake itself and I'm not sure which one goes to the EGR and where the others go.

I'm going off memory as my car still in storage, and it's a Fox. But I thought the 2 hard lines ran to the fuel pressure regulator and the EGR. The FPR had constant vacuum and the EGR did not. Can't help on your 3rd line, but if you could post a couple pic's, might help out.

Allow me to start at the beginning.
I just swapped the AODE out for a 5 speed in the fall. I did not change the ECM.
The engine stumbles now and then but the stumblings do not coincide with the AODE shift points. I have these vacuum lines not connected but they are plugged. I also have no heat for the most part. Sometimes the heat comes and goes.
My idea is to correct the vacuum issue first and see how that effects the other issues, although I did replace the thermostat yesterday. Still no heat.
The pic below shows the lines I mean. I broke one off cos it is brittle and plugged it with a drywall screw.

Is the AODE ECM compatible with the T5 ? I thought the SN stuff was a lot more finicky when it comes to that stuff.
Also, can't really tell much from the pic, do you have have lines running to the regulator and EGR already ?

The only thing that I can suggest is hunt down a vacuum schematic. Making sure your vacuum lines are run correctly. I know I've seen them in some older threads here, might have to dig a little. Wish I could help more, good luck.
